for loop - Countdown Timer won't restart

I am trying to get the two countdown timers countDownP and countDown to run sequentially and multiple times in a for loop from 1 to totTurn times. Each timer I think is started and cancelled appropriately before the next timer is started. Yet the loop will only run through once, even though totTurn is set to 2 or to 3 in the for loop.

Any ideas why?

startButton.setOnClickListener {
    for (i in 1 to totTurn) {
        countDownP = object : CountDownTimer(prepTime, 500) {
            init {
                isClockRun = true
            }

            override fun onTick(msUntilFinished: Long) {
                sUntilFinished = msUntilFinished / 1000
                resultTextViewTimer.text = "${(sUntilFinished / 60)}:${(sUntilFinished % 60).toString().padStart(2, '0')}"
            }

            override fun onFinish() {
                isClockRun = false
                countDownP.cancel()
                countDown = object : CountDownTimer(endTime, 500) {
                    init {
                        isClockRun = true
                    }

                    override fun onTick(msUntilFinished: Long) {
                        sUntilFinished = msUntilFinished / 1000
                        resultTextViewTimer.text = "${(sUntilFinished / 60)}:${(sUntilFinished % 60).toString().padStart(2, '0')}"
                    }

                    override fun onFinish() {
                        isClockRun = false
                        countDown.cancel()
                    }
                }.start()
            }
        }.start()
    }
}
